Common weed in lawns and in pathways. Familiar broad leaves have astringent, diuretic and expectorant properties. Valuable for respiratory and gastrointestinal problems such as asthma, bronchitis, and diarrhea. Also helpful for bladder problems and ulcers. Used externally for skin problems, including ringworm, shingles, and varicose ulcers. Squeezing fresh leaves on insect bites and stings relieves pain and itching almost immediately.
